Database ScalingHorizontal scaling with Postgres replication
Modern applications demand scalability to support growing user bases, real-time responsiveness, and large data volumes. But as applications grow, vertical scaling by adding more compute resources has an upper limit.
Once those limits are hit, you’ll need to figure out horizontal scaling by adding more servers into your environment. As most applications are typically read-heavy, the first step to scaling out your database is by adding read replicas to handle the additional load placed on them.
